SPORT Secondary Cat-Back Exhaust System for BMW M3/G80 M4/G82 & M3/G80 M4/G82 Competition, Typ(e) G234M (with and without GPF).
Consisting of:

• sport exhaust centered (absorption principle) &
• connection tube package with valves &
• Front silencer replacement tubes
• one of five tail pipe sets.

We believe this exhaust configuration is the "sweet spot" on the M3/M4 from Remus Exhaust.  BMW designed the OEM exhaust system as one complete unit up to the rear of the downpipes, this means you will have to your original exhaust to install behind the secondary cats as there is no oem exhaust connection point.  If this is possible for you then this configuration will not dissapoint.  Hear the roar of the remarkable M3/M4 with optimal resonance and exhilarating exhaust sound.  Exhaust valve control with no loss of functionality, the Remus Sport exhaust integrates with your on board electronics so that all existing controls remain in place.  No fiddly remotes, no bypassing your system.  Level up your BMW M3/M4, competition and install a Remus Sport Exhaust.  

Valved connection tubes with spherical connection for mounting of the sport exhaust with integrated valves. Installation/fitting at the original mounting point hangers. The activation of the valves is carried out using the original actuators via the vehicle onboard electronics.

Tube diameter: Original tube Ø 70 mm  REMUS tube Ø 76 mm

ATTENTION
The original exhaust will need to be cut!
When fitting REMUS Sport Exhaust, products in some configurations, for example; turbo-back exhaust systems, cat replacement pipes, GPF-replacement tubes as is designed for use on closed tracks, it is possible you may remove connection to lamda probes connected to the OEM equipment.  For these instances, it is advantageous to carry out an ECU remapping, in order to exploit the optimum performance of the exhaust system and to prevent the check engine from lighting up if you have removed/replaced any lambda probes in doing so.

Axle-back, Cat-back, GPF-back, Secondary Cat-back systems generally do not require tuning and do not interfere with any equipment that reports back to your cars computer and error codes.
